To all whom. t may concern.'

Be it known that I, FRANK UNRUH, a citizen of the United States, residing at New Orleans, in the parish of Orleans and State of Louisiana, have invented certain new and useful Improvements in Pencil-Sharpeners, of which the following is a specification.

Mv invention relates to pencil shar eners and has for its object the provision o a dcvice that is capable of being carried in the pocket and is also provided with means for securing the device to the pocket to prevent loss.

Another object of my invention is the provision of a lpencil Sharpener having its blades capable of being adJusted to resent new cutting edges for operation on t e pencil as the cutting surface becomes dull.

Another object of `my invention is the provision of means for securin a pencil sharpener in the pocket having a so clamping means to secure aI pencil to said securing means.

My invention will be describedA in detail hereinafter and illustrated in the accompanying drawings, in which,

Figure 1 is a top plan vlew of my improved pencil Sharpener; Fig. 2, a side view in elevation; Fig. 3, an end view looking toward the cuttin blades; Fig. 4, a view of the opposite si e of the pencil Sharpener from that shown in Fig. 25 Fi 5, a detail view of the blank from which tie clamping member is constructed and Fig. 6,'.a'detail view of the blank from which the cutting member is formed.

In the drawin s, similar reference charactors will be use to designate correspondingwparts throu hout the several views.

vy improve pencil Sharpener comprlses a strip of steel or other suitable material indicated at 1 that is bent in its middle as shown at 2, and has its two sides formed by said bent portion inclined away from one another toward the free ends of the stri The ends of the strip are then bent sharplr;l as shown at 3 and extended on lanes at substantially right angles to the si es'of the strip and provided with inclined. cutting edges 4 that overlap one another as shown in Fi 3. One of the ends of the strip is rovi ed with an extended tongue on its ower portion shown at 5 that engages the lower portion yof the other end lof the strip to act as `a guide for'said other end.'`

' The 'strip'. v1 'is as stated, formed `of steel 2, y 1 lmanonsHAIiPIiNmr..

or other suitable material capable of holding an vedge and is also slightly resilient in nature so that the sides of the strip may be pressed inwardly toward one another as the edges` of the strip become worn where they cross to present new cutting surfaces for operation on the pencil. It will be understood, that in sharpening the pencil, the point of the pencil is drawn downwardly and across the edges 4 and said edges serve to shave oi the wooden portion of the pencil with the graphite contained therein. The device is likewise provided with a clamping member to hold the blades in adjusted positions as described, and this clamping member is formed of a blank as illustrated in Fig. 5 and will now be more particularly described.

The blank consists of a central plate 6 having laterally extending and integral tongues indicated at 7 and 8. ,Each of the tongues 7 and 8 is rovided on oneqof its sides with tabs 9 and) on .its other side with two tabs 10 and 11, the tabs 10 being-shorter than said tabs 11, and all of said tdbs being intzgral with said ,tonguesw e blank 6 is ormedf'withv outwardly curved extensions 12 at the end farthest removed from the tongues 7 and 8, and 13 and 14 indicate incisions made into the plate 6 and curved inwardly and `toward one another as shown to form leaves 15, attached to said late at the points 16, that are substantial y elliptical in shape as shown. These leaves 15 in forming the complete structure as shown in'Fi s. 1, 2, 3 and 4 are bent outwardly of said p ate and toward one another to form the pencil clips as shown in Figs. 1, 3 and 4, and the points indicated at 17 and 18 at the two sides of the leaves 15 are bent slightly in the opposite direction from the direction of bendmfr the leaves in formino* the pencil clips, andD when the device is bent as shown in Fig. l at 19 to form the clam ing member for the edge of the pocket, t lese points project inwardly so that the are in position to engage the material o the garment and hold the device from accidental removal.

The device for inclosing the sharpening blade is formed b bending the tongues 7 and 8 away from t e plate 6 as shown at 20, and then toward one another at the point between the tabs 10 and 11. The ton es are then bent outwardly away from the s arpening Yblade and secured together by means of rivets or other suitable fastening means said'tongues then. curved "away vfrom. one another as 'shown at 22to provide` ajcla-mp- -ing device )to receive a pencil or theflike.

The' ltabs 11 -when the lclar'nping member is in place on the pencil Sharpener heretofore described engagel the outer surface of one of the sides of the strip of steel, while the tabs 9 and 10 are bent inwardly of the pencil Sharpener and engage the inner surface of said strip of stee to hold the strip of steel securely clamped. When the device is assembled'as shown in Figs. 1, 2, 3 and4, it will be apparentthat it may be carried in the pocket, the tongue formed b the downwardly bent portlon and the p ate 6 forming a clip to secure the device on the upper edge of the pocket, the clamping members formed by the outwardly bent -portions 22 on the free terminals of the tongues 7 and 8 and the leaves 15 operating as encil clips to retain the penci ener, it will be apparent that it 1s held bef tween the thumb and iin .while the pencil is tofore :described, and that the clamping V4member formed fr qnp'iegci thisjpateat majP be obtained 1,01'

' Havin thus described my invention, what I c aim is v 1. In a pencil Sharpener, a strip of steel bent on itself and having 1ts sides inclined slightly from one another, the terminals of said strip of steel then bent to overlap one another and provided with cutting surfaces, said cutting surfaces being converging and a clam ing member inclosing said bent strip of stee and slidably mounted thereon.

In testimony whereof I aiix my signature in presence of two witnesses.
